Medical billing services in Ohio
Short answer
Medical billing services in Ohio run through one state front door: every EDI claim, fee-for-service or managed care, goes to ODM's EDI vendor and is routed by the Fiscal Intermediary to one of seven Next Generation MCOs or adjudicated as fee-for-service, with a 365-day filing window and a Medicaid prompt pay standard of 90 percent of clean claims in 21 days.
Add EVV claims validation that denies a home care visit without a matching record, telehealth that wants the GT modifier and the practitioner's place of service, and MyCare claims on the same front door since January 1, 2026. Remitwright gives a dedicated biller who works those rules, serving Ohio practices remotely. Rules for other states are on the medical billing services by state page.

Ohio Medicaid
Ohio Medicaid is run by the Ohio Department of Medicaid (ODM). Fee-for-service claims and provider enrollment go through the Provider Network Management (PNM) module1, at ohpnm.omes.maximus.com. Next Generation managed care, launched February 1, 2023: seven managed care organizations operate under one ODM provider agreement, with OhioRISE for children and youth with behavioral health needs and Gainwell Technologies as the Single Pharmacy Benefit Manager for every plan2. All EDI claims, fee-for-service and managed care, go to ODM's EDI vendor, Deloitte; the Fiscal Intermediary routes managed care claims to the plan and adjudicates and pays fee-for-service claims. Direct-entry fee-for-service claims start in the PNM module, while direct-entry managed care claims and prior authorizations go into the plan's own portal. Providers may contract with any or all of the seven MCOs.
Fee-for-service filing limit: 365 days from the date of service for fee-for-service claims; ODM applied the same 365-day window to community behavioral health claims billed to the Medicaid managed care plans3. Under OAC 5160-1-19(C)(2)(ii), a denied fee-for-service claim may be resubmitted within 180 days of the denial if the original claim was received timely, even when that falls past the 365-day mark. Each MCO's provider manual and contract governs its own deadline, so confirm the plan limit before relying on the state window.
Managed care plans2
- AmeriHealth Caritas Ohio, Inc.
- Anthem Blue Cross and Blue Shield
- Buckeye Community Health Plan
- CareSource Ohio, Inc.
- Humana Healthy Horizons in Ohio
- Molina Healthcare of Ohio, Inc.
- UnitedHealthcare Community Plan of Ohio, Inc.
Each plan is credentialed separately, has its own portal and its own appeal route. A practice that joins Ohio Medicaid through one plan is not in network with the others until each contract is in place.
Commercial payers and plan payment standards
The largest commercial payers in Ohio by reported market share6: Anthem Blue Cross and Blue Shield, Medical Mutual of Ohio, UnitedHealthcare, Humana, CareSource, Molina Healthcare of Ohio. No two of them share a provider manual: filing windows, corrected-claim processes and appeal levels are set payer by payer, and the timely filing limits table lists verified deadlines, each with its source.
For Medicaid managed care, the clean-claim payment standard under the Ohio Medicaid MCO Provider Agreement, Appendix L section 10, applying 42 CFR 447.46: 90 percent of clean claims paid or denied within 21 calendar days, 99 percent within 60 days, 100 percent of all claims within 90 days4. Applies to Ohio Medicaid MCOs for network and out-of-network providers unless the provider contract sets another schedule, measured separately for nursing facility, behavioral health and all other claims, and reported to ODM quarterly. Commercial plans answer to a different law: the Department of Insurance rule on unanticipated out-of-network care points them to R.C. 3901.38 to 3901.3814, Ohio's prompt pay sections, so commercial claims are tracked against those sections and the payer contract, not against this Medicaid standard. In A/R follow-up, a managed care claim that is past that standard is raised with the plan, with the contract term cited.
NEMT and home care in Ohio
Non-emergency medical transportation. Split by benefit. Ambulance and wheelchair van transport is covered under the general Medicaid benefit and paid by ODM or the member's managed care organization; other non-emergency rides (taxi, van, sedan) may be covered by the MCO for managed care members; for anyone whose ride is not otherwise covered, the county department of job and family services (CDJFS) provides NEMT assistance on ODM's behalf, from actual rides to fuel subsidy depending on local resources8. Payment for CDJFS rides is negotiated with vendors under county procurement; wheelchair van rates are set by the State. Each wheelchair van provider and each CDJFS vendor must pass the LEIE exclusion check, hold valid driver licenses, screen for disqualifying offenses and obtain a BMV certified driving record for every driver. The state plan names no statewide broker. The NEMT billing in Ohio page covers trip documentation, broker claims and reconciliation.
Electronic visit verification. State system plus certified alternate vendors. Sandata runs the Ohio EVV system and the Sandata Aggregator, the single collection point that matches claims to visits; an agency may use an Ohio-certified alternate EVV vendor, which must send its visit data to the Sandata Aggregator, and independent providers may register to use an alternate vendor as well9. Required under the 21st Century Cures Act for Medicaid-paid personal care and home health services. The enhanced EVV system went live July 1, 2024. ODM phased in EVV claims validation in seven phases from March 1, 2025; a claim for an EVV service must have a matching visit record at submission or it is denied. Phase 5, covering DODD waiver services such as homemaker/personal care and waiver nursing, began October 1, 2025. ODM's February 23, 2026 EVV Stakeholder Workgroup deck adds Phase 6, direct-bill services paid by ODM and the Ohio Department of Aging, from January 1, 2026, and Phase 7, MyCare service claims, from March 1, 2026, which completed the rollout. See home care billing in Ohio for waiver programs, EVV exceptions and authorizations.
Rules that change how Ohio claims are billed
Surprise billing under R.C. 3902.50 to 3902.54 and ODI rule 3901-8-175
Ohio's own surprise billing law covers unanticipated out-of-network care, including emergency services and out-of-network lab work ordered by an in-network provider. The plan sends an initial payment directly to the provider; the provider then has 30 calendar days to notify the plan that it wants to negotiate, or the payment counts as accepted. If negotiation fails, eligible claims, bundled up to 15 at a time, can go to arbitration through the Superintendent of Insurance, with a decision due within 30 calendar days and the non-prevailing party paying 70 percent of the arbitrator's fee. The patient's cost sharing stays at the in-network amount whatever the outcome.
Telehealth billing wants GT and the practitioner's place of service10
ODM's telehealth billing guidelines under OAC 5160-1-18 apply to fee-for-service dates of service on or after January 1, 2026. In most cases the GT modifier identifies a telehealth service, the place of service is the practitioner's physical location, and POS 02 and 10 are not accepted when Medicaid is the primary payer unless a provider-specific guideline says otherwise. A patient-location modifier is required when the patient is at home, at school, in a hospital, in a nursing facility or in an ICF. The MCOs cover the same telehealth services but may set different billing requirements.
Revalidation notices arrive 120 days out, by mail, email and in PNM11
ODM sends a revalidation notice about 120 days before the deadline to the correspondence address and email on file and posts it in the PNM module correspondence folder under Enrollment Notices; each provider number revalidates separately. Organizational providers pay the federal application fee at revalidation ($750 for 2026) unless they paid Medicare or another state's Medicaid within two years and submit proof. A provider that does not revalidate is terminated, and reactivation takes effect only from the date the provider completes it, with no retroactive enrollment, so claims in the gap are lost.
Next Generation MyCare moved to the One Front Door in 202612
MyCare Ohio, the program for people with both Medicare and Medicaid, joined the Next Generation program on January 1, 2026 in the 29 existing MyCare counties, with ODM's schedule adding the remaining counties monthly from April 2026 to reach the whole state in August 2026. Anthem Blue Cross and Blue Shield, CareSource and Molina Healthcare of Ohio are available statewide; Buckeye Health Plan continues only for its existing members. All EDI MyCare claims, regardless of date of service, must go through ODM's One Front Door from that date, routed by the Receiver ID in the header and the Payer ID in loop 2010BB.
Remittance advices and rendering-provider affiliations live in PNM1
Since February 21, 2023, all fee-for-service remittance advices are available in the PNM module. ODM also requires a group, organization or hospital to fully execute every step when affiliating a rendering provider in PNM; an incomplete affiliation causes claims payment issues, so a new clinician's first claims depend on that affiliation being finished, not just started.
